The UL listed Intelligent Fire Alarm System. D-TECTRON fire alarm systems can be configured with just a few devices for small size building applications, or networked with many devices to protect a large campus or a high-rise building. Simply add additional peripheral equipment to suit the application. Our advanced technology delivers supports the installers to do complete installation easily through simple steps. The inherent fault-tolerant characteristics of Analog/Address- able Technology boosts the reliability of D-TECTRON fire alarm systems. When combined with D-TECTRON smoke and heat detectors, these systems deliver a level of reliability and dependability for both small to medium size applications.
The DT811 input module monitors a single contact. The input line is monitored for open line faults and ground faults, and the contact must thus be wired with an end of line resistor. It is an intelligent addressable module and takes one address on the Signaling Line Circuit (SLC) orData Communication Link (DCL) of the fire alarm control panel. The DT811 is a UL listed device according to UL864 for Fire Protective Signaling Systems for indoor use. The type of the input contact is configurable.
